“…It is possible that regulation of CAT transcription is only sufficient to maintain its activity (Defo et al, 2015). It is not surprising that there are different responses at transcriptional and catalytic levels of some antioxidant genes (Craig et al, 2007;Giuliani et al, 2013;Hansen et al, 2007;Regoli and Giuliani, 2014;Zheng et al, 2016c). The mismatch between antioxidant gene expression and enzyme protein level may be involved in time-lag effect between transcription and translation, and/or RNA stability (Nam et al, 2005).…”

“…Extractions of total RNA from liver and first strand cDNA synthesis were performed according to the methods in our recent study with slight modification (Zheng et al, 2016c). Q-PCR reactions (20 μL for 30 s. Each reaction was verified to contain a single product of the correct size using agarose gel electrophoresis and have no significant differences in amplification efficiencies.…”

“…For example, Zn is essential as a cofactor for many enzymes (e.g., Cu/Zn-SOD) and also serves an important function in transcription of many genes involved in cellular protection 4 against reactive oxygen species (ROS) (Chung et al, 2005). However, excessive Zn in the aquatic environments can be toxic, which has a devasting effect on fish species, inducing oxidative damage (Zheng et al, 2016b;Zheng et al, 2016c;Zheng et al, 2011). Thus, it is possible that there are differences in Zn and Cd induced oxidative stress responses even at the same toxic level of a low dose, however, these warrant investigation.…”

“…The activation of endogenous antioxidants in response to fasting has been reported for several species. For instance, fasting leads to increased SOD activity in the plasma of emperor penguins 60 , increased hepatic CuZnSOD expression (at both mRNA and activity levels) in yellow croakers 61 , and increased total SOD activity in liver and gills of brown trout 62 .…”

Juvenile tegu lizards (Salvator merianae) experience gradual and mild temperature changes from autumn to winter in their habitat. This tropical/subtropical reptile enter a state of dormancy, with an 80% reduction in metabolic rate, that remains almost constant during winter. The redox metabolism in non-mammalian vertebrates that hibernate under such distinguished conditions is poorly understood. We analyzed the redox metabolism in the intestine of juvenile tegus during different stages of their first annual cycle. The effect of food deprivation (in spring) was also studied to compare with fasting during hibernation. Both winter dormancy and food deprivation caused decreases in reduced glutathione levels and glutathione transferase activity. While glutathione peroxidase and glutathione transferase activities decreased during winter dormancy, as well as glutathione (GSH) levels, other antioxidant enzymes (catalase, superoxide dismutase and glutathione reductase) remained unchanged. Notably, levels of disulfide glutathione (GSSG) were 2.1-fold higher in late autumn, when animals were in the process of depressing metabolism towards hibernation. This increased “oxidative tonus” could be due to a disruption in NADPH-dependent antioxidant systems. In dormancy, GSSG and lipid hydroperoxides were diminished by 60–70%. The results suggest that the entrance into hibernation is the main challenge for the redox homeostasis in the intestine of juvenile tegus.

“…The curve of crude fat levels of three groups is presented in Figure . Crude fat of three group samples showed no significant difference at 0–48 hr ( p > 0.05), and at the 56 hr crude fat of group 3 was significantly lower than those of groups 1 and 2 ( p < 0.05), the PY out water for a long period of starvation consequently decreased fat (Zheng et al., ). A significant difference in lipid content was observed in groups starved for 56 hr.…”

The supply chain of shellfish is complex, with animals being subjected to several stressors during the depuration, temporary keeping, and waterless‐low‐temp transportation processing. In this paper, the recycled water system for depuration and temporary keeping was used to realize both depuration and temporary keeping of Patinopecten yessoensis. The samples were divided into three groups based on three different pre‐process involved: samples in group 1 were depurated for 48 hr straight, whereas those in group 2 were first depured for 24 hr and then cooled for 24 hr; samples in group 3 was directly kept in a polyethylene insulation box. Then group 1 and group 2 were transported in a 3L polyethylene insulation box with ice packs (250 ml) to study the quality of transport based on the different pre‐process. As a result, in group 1 (depuration for 48 hr), the first death occurred after 56 hr, and all shellfishes died after 102 hr with total bacterial density of 2,630 CFU/ml. In group 2 (depuration for 24 hr and temporary keeping for 24 hr), the first death occurred after 104 hr and the total number of bacteria was increasing steadily within 0–104 hr. After 120 hr, all shellfishes died with total bacterial density of 1,090 CFU/ml. In group 3 (directly transport), all shellfishes died in 64 hr. The total number of bacteria in groups 1 and 2 declined significantly in the depuration process. The bacteria number (p < 0.05) in group 3 was significantly different from that in groups 1 and 2. The crude protein, crude fat, and glycogen of all groups declined. However, compared to groups 1 and 3, the consumption of glycogen in group 2 (p < 0.05) was delayed by the gradual cooling procedure. Those results prove that the depuration and temporary keeping procedures can improve the sterilization of the bacteria. The survival rate is less sensitive to the temperature change. The results provide satisfactory references for the P. yessoensis’ quality studies with depuration, temporary keeping, and waterless‐low‐temp transportation technologies.
